nim#init executes nimscript on load

[zargot]

When opening a nimscript file (*.nims) into vim, all "exec" statements are executed. This makes editing nimscript files very impractical, and poses a huge security risk.

example.nims:

exec "touch a_wild_file_appears.txt"
exec "rm -r ~/my_important_projects"

This seems to occur in autoload/nim.vim:nim#init:

  let cmd = printf("nim --dump.format:json --verbosity:0 dump %s", s:CurrentNimFile())
  let raw_dumpdata = system(cmd)

My current workaround is to comment out the whole function call in ftplugin/nim.vim:
"call nim#init()

Thanks for your time.

This was reported as an upstream issue in Nim. Another mitigation we can apply here is to start treating nims files as a different language mode.

Any progress on this?

I forked this and just removed all IDE functions. There's just:

• Syntax highlighting
• Indentation
• Compiler

It's just a basic version of this.
